"Cannot access memory beyond the end of bootstrap direct-map area"

grub-legacy is fine ..

The xen client XCI tree uses grub2. I seem to recall there was a bug that 
needed fixing in grub2 to make it work reliably, but I thought this was 
up-streamed. It's worth looking to see if there are any grub2 related patches 
in the XCI tree, though.
